This is a really cool service!

One nitpick, though: in the live demo of the circular cropped face, it appears that the face is slightly off center, whereas in the first promo image of the article [1] it appears more zoomed out and perfectly centered. I tweaked the url parameters a bit to try to mimic the promo [2], but the weighting of the image feels a little off -- towards the top right. If the auto face detection doesn't produce perceptually centered images consistently, that is an important caveat, and the promo should reflect that.

Reading the headline I thought the program would produce stylised pics like this:

Question: is it possible to have a computer draw such images?

Thanks for your comment. I updated the promo in the blog post to reflect the exact result from: https://assets.imgix.net/blog/woman-hat.jpg?w=640&w=250&h=25...
